I was talking about the pruning standard, thought that was obvious.
Different sites -> different standards -> no hypocrisy.
Exactly, the ISA is an industry organization run by people from the industry.
The pruning standard in someones yard should be higher then that used out in the middle of nowhere.
I complain about bad tree work, but I complain about the cost of electricity too. I want them to manage the cost reasonably.
Good luck getting them to pull the ad. I cant wait to see the average tree "care" company using this type of equipment in my neck of the woods. I will be the first on the job site to raize hell...
An average tree company could not afford to own one, like a bucket, you need contracts to run the thing on a regular basis, meaning row and maybe fire trail contracts. The Giraffe is followed by a brush hog....mile after mile of "mindless" machine operation. (that was hyperbole, you need a skilled operator in both rigs to make money)
The ISA does seem a bit hypocritical at times.
If you would follow what they say, on regular basis, then you would see that they represent more then just the residential climber. One of my many complaints is that we often get lost in the mix of the bigger companies with more influance.
Some treatments do not fit the "tree trimming 101" model that Shigos book excerpts have become. Heck, a lot of Shigo's work is dated, something that the current ISA researchers have built upon.
Hydro, to thier credit, does not accept stubs or flush cuts anywhere
That is good, but a stub is always better then a flush, at least you are not cutting into trunk wood. And with a stub, it may sucker up and prevent scalding of the trunk.
